Discuss the role of the NTCA and scientific institutions in inter-State wildlife translocation. What challenges arise after release?

Inter-State translocation means moving wild animals from a source population in one State to habitat in another. It has become India's main tool for restoring reserves that lost their tigers. In October 2026, tigress T138 was moved from Valmiki (Bihar) and released into Buxa (West Bengal) [1]. The case shows that the move itself is only the first step. What decides success is science-led management after release.

Role of the NTCA

• Statutory anchor: The NTCA is a statutory body. It gives Project Tiger's directives legal force and makes the Centre and the States accountable for how tiger reserves are run [3].
• Precedent: It led India's wild-to-wild tiger reintroductions in Sariska and Panna [3]. This experience now carries over to Buxa under the Tiger Reintroduction Programme [2].
• Federal broker: Bihar is the donor, West Bengal the recipient, and the Centre the technical backer. This is cooperative federalism in conservation [1].

Role of scientific institutions (WII)

• Site preparation: The WII and the NTCA have supported West Bengal's Tiger Augmentation and Recovery Project since 2018 [1].
• Founder selection: Young animals of breeding age are chosen. T138 is about three years old [1].
• Monitoring: Telemetry, camera traps and field tracking check whether she settles [1]. Releasing tigers in phases lets managers adjust the plan as they go.

Challenges after release

• Root causes may persist: Buxa lost its tigers to habitat fragmentation, land-use change and prey decline [1]. Releasing a tiger fixes none of these.
• Prey and conflict: If wild prey is scarce, tigers turn to cattle or leave the reserve. Local support then falls.
• Small founder group: One tigress cannot breed. The sex and source of the next three tigers have not been disclosed [1]. Without corridors to other forests, the population risks a genetic bottleneck.
• Donor cost: Taking breeding females out can weaken the source reserve's own population.
• Premature tourism: The release has already been linked to tourism [1]. Visitor disturbance can push a tigress that is still settling to stray.
• Opacity: If monitoring data stays unpublished, a quiet failure can go unnoticed.

The NTCA provides the legal framework and the WII provides the science, but the real test begins after release. Four steps would turn a symbolic release into a self-sustaining population: publishing telemetry results, showing that prey has recovered before further releases, securing landscape corridors, and assessing Buxa through the NTCA's Management Effectiveness Evaluation [4]. That would honour Article 48A and SDG 15.
